“I love my slow feeder. I use it on my Ek43 with SSP HU burrs and have noticed a big improvement to the clarity and consistency of my brews. For me the slow feeder has been as significant of a change as different burrs in my grinder and at 1/4 of the cost!”
We’ve been hooked on slow feeding since James Hoffman’s post on slow feeding with the Niche Grinder a few years ago (link). Since then Lance Hedrick and Baristle Hustle have noted improvements with slow feeder as well and have championed slow feeding for notable gains with any grinder. Cleaner brews with less fines? More sweetness? Yes, please!
Manually slow feeding gets old pretty quick though. So we got to work after many exploring many concepts and built the world’s first electric slow feeder with a rotating angled carousel. As we launch our next slow feeder design, we can’t wait for you to experience the benefits of slow feeding and for this to become the new standard in home brewing!
Less fines and heat, more clarity and aroma
Slow feeding has shown improvements in grind quality through a number of means including minimising fines that increase the risk of over-extraction and reducing the heat generated during the grinding process. (Lance Hedrick video link, Barista Hustle paper)
Baristas all over the world have tasted the difference. What’s been missing is a way to automate the process for better consistency.


Adjustable Feed Speed
Find your sweet spot with the adjustable feed dial on our slow feeder along with a switch so you can leave feed rate at your preferred setting. If your grinder can keep up with higher feed rates, crank the dial up for a total feed time of 30s for a 20g dose.
Don’t mind waiting a few minutes for maximum flavour? Slow it right down and prep your setup while the slow feeder feeds away!
Battery operated for wire-free operation
The Madkat Slow Feeder works with two AA batteries so you don’t have to worry about wires. Replacement is easy with a snap fit cover!

Highly recommend to anyone that wants to continue improving their coffee knowledge and quality of brews."

"Bought this for my Zerno Z1 and I’m very happy with the results! My brews are clearer and tastier than ever. It was also very easy contacting and ordering MadKat. Highly recommended."
Kyle Gosiaco
"Having tried almost every slowfeeder, this is the one that suits my palate the best. The speed control is both slow and fast enough for different grinders. (I prefer grinding without pausing while bean by bean)
100% recommended!"
Edison Hou
"My P80 has been upgraded into an even more incredible grinder.
This slow feeder is extremely simple to install and operate, and it’s very easy to fine-tune it to your ideal feeding speed.
As a result, the cup quality has become remarkably clear, with delicate flavors expressed more distinctly than ever."
